Abstract
In a printing apparatus a method and apparatus for applying a loading force to a first roller assembly to move a first roller of the first roller assembly into nip engagement with a second roller of a second roller assembly, the first roller assembly having a first fiducial element for locating the first roller and the second roller assembly having a second fiducial element complementary to the first fiducial element for locating the second roller, the first roller assembly being supported by a hook and pin connection engagement that supports a carriage, which carriage supports the first roller assembly for rotation about an axis external to the first roller. Upon applying of a loading force to the first roller assembly along a line which in a planar diagram of the first roller and load force passes between the center of gravity of the combination of the first roller assembly and the carriage and the first fiducial element to create a moment about the axis so that the carriage and the first roller assembly rotate together toward contact of the first fiducial element with the second fiducial element; and upon continuing to apply the loading force, the first fiducial element and the …
